That's not true. The medical stone non-stick pans sold in the market are all mineral particle non-stick pans and aluminum alloy pans. It is not a real medical stone pot. If it is really a pot made of medical stone, its disadvantage is not only slow heat conduction, but also very heavy pot feeling, which is not suitable for daily cooking. First of all, we need to know the ontology of the so-called medical stone non-stick pan. It is mainly a non-stick pan composed of mineral particle non-stick coating and aluminum alloy pan body. This combination can not only meet the needs of fast heat conduction and light pot body in daily use, but also use natural mineral particles on the non-stick layer, which is more reassuring than other chemical non-stick layers. Second, keep your eyes open. Some merchants pretend that the medical stone does not stick to the pot, but in fact, his non-stick layer is just like a stone, which has nothing to do with the stone. Don't choose this one (choose the one marked with non-stick layer of mineral particles), and you can choose it only after a test certificate proves that its coating is safe and non-toxic.
